Product Information:
The TC-4 is CIRCUITRON's TORTOISE Turnout Direction Alternator. It contains only one control terminal.
When the control terminal is connected to a detection circuit, the TORTOISE will be thrown one way the first
time a train is detected, and then will be thrown the opposite way the next time a train is detected. In this
way, trains can be made to automatically travel alternate routes each time around a layout.
